Kimber carbon barrel

I posted this in the gunsmithing but thought it might be better in here. The previous owner of my kimber royal II didnt not keep it oiled like he should have. I have tried a few different polishing things I have read about but cant get all the discoloration off. I was thinking of getting some of the birchwood casey perma blue to cover up the discoloring. Is there any reason I should not do this? If not does anyone have any tips for applying it? Thanks

I've seen this before. I'm more concerned with how a guns shoots that if there's carbon scoring on an internal part that nobody will see anyway. I do know a guy who's pretty anal and had this on one of his Kimbers, and Kimber offered to polish it out for free. He took them up on the offer. It took about six weeks, but it looked good as new and only cost him shipping one way.

I'd suggest that route if it's going to make you lose sleep. Trying to apply a blued finish will probably look uneven because the stains will likely show through the blued finish. Personally, I'd just keep shooting it.

I had a little of that near the bushing on my custom ii. I sent it in for warranty work on something else, and the gunsmith told me he also refinished the barrel because of discoloration. It came back looking new. No charge.

By the way, that is typical of good carbon steel like 1095 (I don't know what kind the barrel on a kimber is made from though). That stuff is also tough as hell compared to stainless. I wouldn't worry about it, but keep it oiled.

If it were 4150, there'd be less oxidation. Then again Kart or Bar-Sto Precision barrels would not have issues.
